In the recent automotive industry, a braking system is considered to be very important in terms of the safety of the driver. FEA is a basic simulation of a physical component and is used for performing mechanical analysis. FEA is very essential before the production of any component of a vehicle. In this paper, a ventilated and drilled type of disc brake is taken as the component which has been thermally analyzed. This thermal analysis is done with the use of Ansys Workbench 2020 R1 and the component is modeled using the SolidWorks software. In this paper, a brief idea about the effect of different meshing sizes as well as the type of meshing using finite element analysis is considered and consequently, the thermal analysis of the same has been calculated. The results obtained illustrate the effect of the difference in mesh size and the type and how it plays an important role in the analysis of any component.
